Ryan Blue commented on PARQUET-129:
-----------------------------------
[~wdaehn], if you'd like to pick this up and implement something to get around
the restriction, that would be great. A little more work has been done for this
using Avro's logical types to break circular references. Check out this test
for an example:
https://github.com/apache/parquet-mr/blob/master/parquet-avro/src/test/java/org/apache/parquet/avro/TestCircularReferences.java
That doens't happen transparently, but I think that's similar to what you're
proposing.
